LOSPOR — Large Open Source Perioperative Register

LOSPOR is a free, open-source personal anaesthetic case log for learning, portfolio, and reflection. It is designed for anaesthesiologists and is available in both English and Bulgarian.

What does it do?​

LOSPOR guides the anaesthesiologist through three forms for each case:

  1. Preoperative assessment — patient demographics, diagnosis, airway evaluation, risk scores, vitals, and labs
  2. Intraoperative record — real-time timetable of vital signs, drugs, agents, infusions, and fluids
  3. Postoperative recovery — Aldrete score, pain, disposition, and handover instructions

At the end, LOSPOR automatically generates a printable two-page anaesthesia protocol (PDF) containing all entered data in a standardised, professionally laid out document.

Who is it for?​

  • Anaesthesiologists recording cases and generating protocols
  • Anaesthesia nurses contributing to case records
  • Heads of department overseeing institutional cases and assigning staff
  • Researchers accessing the de-identified / pseudonymised perioperative dataset

How does it work?​

Clinician registers → Opens new case → Fills preop form
  → Fills intraop form (live timetable) → Fills postop form
  → Protocol generated → PDF printed → De-identified data stored

Patient-identifiable information is never stored. The printed protocol leaves patient identity fields blank — fill them in by hand after printing.

The live application is available at app.lospor.org.

Open source​

LOSPOR is licensed under the AGPL-3.0 licence. The source code is available on GitHub. You are free to self-host it for your institution — see the Self-hosting guide.

What LOSPOR is and isn't​

Is: A personal log for anaesthesiologists to record cases without direct patient identifiers, track learning, and generate a printable case summary.

Is not: A clinical record system, a patient management tool, or a certified medical device.

Privacy & GDPR​

LOSPOR is designed with GDPR principles in mind:

  • Patient names and ID numbers are never stored in the database
  • Each case is shown by a pseudonymised case code (e.g. 2026-0001); internal user, institution, and timestamp linkage is retained for access control, audit, and research governance
  • LOSPOR targets GDPR-oriented deployment. The hosting region, database region, AI inference region, and sub-processors depend on the deployed configuration. The default configuration uses EU-region providers (Supabase, Vercel, Mistral La Plateforme), but regional AI inference may fall back to global endpoints if the configured region is unavailable.
  • Users must be authenticated to access any data
  • GDPR rights (data export, account deletion) are available under Settings → Privacy & Data
